IMPROVEMENT IN PAN ELING-MACHINES.

Specification forming part of Letters Patent N0. 217,005, dated July 1,1879; application filed June 7, 1878.

To all whom it may concern:

Be it known that I, J OHN W. GEOFF, of Albion, in the county of Calhounand State of Michigan, have invented a new and valuable Improvement inPaneling-Machines; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference be ing had to the annexed drawings, making a part ofthis specification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a front elevation of myinvention; and Fig. 2 is a side elevation of the same, partly insection.

This invention has relation to paneling-machines; and the object thereofis to provide an attachment to this class of machines by which the panelcan be readily cornered without the necessity of removing the panel fromthe machine and cornering it with a jackplane or other similar tool,which has generall y" been the custom.

The invention therefore consists in the general construction andarrangement of the several parts constituting the device, as will behereinafter described, and subsequently pointed out in the claim.

In the accompanying drawings, A represents the bed-plate or top of themachine; B, the rest or support, and O pressure-bar for holding thepanel in position, which is repre sentcd at D, these several parts beingof the ordinary construction, and therefore further description of themis deemed unnecessary.

The attachment which embodies my invention is secured underneath thebed-plate A, and consists, in part, of a horizontal shaft, a, carrying apulley, 0, upon one of its ends, over which is secured or passes a beltconnecting with a suitable driving-power, and upon the opposite end isrigidly connected a cutter-head, E, carrying upon its opposite sidesknives c 11, secured to said head by bolts 0. These knives are arrangedwith their inclined cutting-edges in opposite directions, so that duringthe rotation of the head E, and as the ends of the knives pass upthrough the bed-plate, both sides of the panel will be cornered as thecutting-edges come in contact therewith.

The shaft a has its bearing in a standard, F, which is made verticallyadjustable by an adyusting-scremf, having a button at its upper end,which engages in a recess in. the inner face of the standard F. Thescrew f passes through a screw-threaded perforation in a guide-plate, g,and is operated by a hand-wheel, h, at its lower end. The standard isguided in its vertical adjustment by ways i upon a support or rearplate, G.

The standard F is held in position, after being properly adjusted, by aset-screw, is, passing through an elongated slot, Z, in said standardand through the support or rear plate, G.

The cutter-head E runs in a reverse direction of the main cutterhead ofthe panelingmachine, which prevents slivering the panel and draws verylittle in its out. The ready adjustability of the cutter-head increasesor diminishes the cut, as required, which is con sidered very essentialin the successful operation of cornering panels.

7 Having now fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isg In a panel-cornering attachment,the rear plate, G, attached to the bed-plate A, and provided with theways i and perforated guideplate in combination with the standard F,recessed on its inner face, and having at its upper end thejournal-bearing for the shaft to,

screw f, having a button at its upper end, and

adjustable cutter-head E, having knives 0 cl, arranged as described,substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
